  Electrically Tunable Liquid Lens Based on Navier-Stokes Fluidic Control with Graphene-HBN Heterostructures
  Author(s): Chur Chin*
  
  Adaptive optical systems demand compact, fast, and energy-efficient tunable lenses for applications ranging from smartphone cameras to biomedical imaging. Traditional mechanical autofocus mechanisms suffer from bulkiness, power consumption, and limited response speed. Here, we present a novel electrically tunable liquid lens based on Navier-Stokes fluidic control integrated with graphene-hexagonal boron nitride (hBN) heterostructures. By applying voltage-controlled electro-osmotic flow to liquid crystal (E7) layers positioned above graphene electrodes, we achieve focal length modulation from 10 mm to infinity within 10 milliseconds at driving voltages of 1.5-10 V. The graphene- hBN interface serves dual functions: transparent electrode for fluid actuation and quantum-enhanced optical phase modulator. Our design eliminates mechanical moving parts, enabling ultra-thin form factors suita.. Read More»
